I personally don't know the names of the 1,000 monkeys the State gave the lap-tops to, but here is 3 books that can help you prepare, ( in order of best to OK):
1) Barron's Police Officer Exam
Has some sample tests plus other tips that covers the basic hiring process
2)Cliffs Police Officer Examination Preperation Guide
Just like the first but has stuff like nutrition, excersises, Sample oral board questions
3) Norman Hall's Police Exam Prep Book
Its OK, a little of everything, but not that detailed.
I purchased mine from Borders for about $15. You can get them from a library, but buying is better. If its yours you can use the practice sheets, make notes, and reveiw the portions as you advance through the hiring process.
